Jumping genes do most of their jumping, not during the development of sperm and egg cells, but during the development of the embryo itself. The research challenges standard assumptions on the timing of when mobile DNA, so-called jumping genes, insert into the human genome.

African bird species could struggle to relocate to survive global warming because natural features of the landscape will limit where they can move to, according to new research.

Scott Bauer USDA/ARS What is biology? Simply put, it is the study of life. With that in mind, how do we know if something is living? Is a virus a living thing? What are the characteristics of life? Living organisms have the ability to be organized, take and use energy from the environment, grow and develop, reproduce, respond to stimuli, and adapt to the demands of an environment. Living things include both the visible world of animals and plants, as well as the invisible world of viruses and bacteria. The foundation of biology as it exists today is based on five basic principles. They are: Cell Theory: all living organisms are composed of cells. The cell is the basic unit of life. Gene Theory: traits are inherited through gene transmission. Genes are located on chromosomes and consist of DNA. Evolution: any genetic change in a population that is inherited over several generations. These changes may be small or large, noticeable or not so noticeable. Homeostasis: ability

In a discovery that could lead to new treatment approaches for depression, researchers in Australia have shown that Internet-based therapy programs are as effective as face-to-face therapies in combating the illness. Patients in a clinician-assisted Internet-based treatment program experienced rates of recovery similar to those achieved by face-to-face therapy, the research found.

A research group based at the university of Granada, in cooperation with the Neurology Unit of the San Cecilio Hospital of Granada and the Department of Experimental Sciences of the University of Jaen, is studying the Neurobiology of Parkinson's disease (PD). They have developed a non-invasive method for serological diagnosis of Parkinson's disease, which is being patented by the University of Granada.

'Taking out the trash' takes on a whole new meaning, as investigators at The cancer institute of New Jersey (CINJ) and Rutgers, The State university of New Jersey, have discovered that a waste disposal protein is the key to cancer tumor suppression in a process known as autophagy. CINJ is a Center of Excellence of UMDNJ-Robert Wood Johnson Medical School. Autophagy is a process in which cancer cells eat themselves.

BACKGROUND: Low-density lipoprotein (LDL) is the so-called 'bad cholesterol' often linked to medical problems like heart disease and clogged arteries. Cells in the liver produce a specific receptor that sticks to LDL and removes it from the blood, lowering cholesterol levels. Statin drugs also reduce LDL cholesterol levels by boosting cells' production of the receptor.
